Meal Replacement Shakes After Dental Surgery

Can Meal Replacement Shakes Help with Dental Surgery Recovery?

A liquid or soft foods diet is often required following dental surgery.

In many cases, patients are unable to chew solid foods due to tenderness and swelling.

Ice cream and pudding may suffice for a few meals, but you are eventually going to need to start adding healthy, nutrient-rich foods back into your diet.

This is because your body needs calories and nutrients, especially protein, to heal (J Int Med Res, 2019).

High protein foods like yogurt, scrambled eggs, and creamy nut butter are all great dietary choices if you just had a root canal, dental implants, jaw surgery, or your wisdom teeth removed,

Meal replacement shakes are also a good option, especially if you are on a strictly liquid diet.

Adding a meal replacement shake to your diet is an easy way to fill in nutritional gaps and ensure that you are getting the calories and nutrients you need to heal.

Meal Replacement Powder can also be added to soft foods like yogurt and oatmeal for a nutritional boost.

Not all meal replacements are created equal, however.

What Are the Best Post-Op Meal Replacement Shakes?

Many meal replacements contain ingredients that can cause inflammation, thereby slowing down the healing process (J Invest Dermatol, 2016).

Among these ingredients are food additives like emulsifiers, thickeners, and flavors.

🚫 Avoid Food Additives

Regularly eating food additives can alter the composition of your gut microbiome (North Clin Istanb, 2019).

This can lead to gut dysbiosis, or an imbalance in gut bacteria, which is a leading driver of inflammation (Biomed Pharmacother, 2022; Cell Host Microbe, 2016).

Inflammation occurs because gut dysbiosis damages your intestinal lining (Biomed Pharmacother, 2023).

This, in turn, allows harmful substances to cross into your bloodstream, where your immune system detects them as foreign invaders and mounts an inflammatory response.

⚠️ Here is a list of the most common food additives in meal replacements:

• acacia fiber
• acacia gum
• acesulfame potassium
• artificial flavors
• ascorbic acid
• aspartame
• calcium carbonate
• carrageenan
• cellulose gum
• dextrin
• dicalcium phosphate
• dipotassium phosphate
• erythritol
• gellan gum
• guar gum
• gum arabic
• inulin
• locust bean gum
• maltitol
• maltodextrin
• mono- and diglycerides
• ‘natural’ flavors
• rice bran extract
• rice dextrin
• rice hulls
• rosemary extract
• silica
• silicon dioxide
• sodium alginate
• soluble corn fiber
• sorbitol
• soy lecithin
• sucralose
• sunflower lecithin
• tocopherols
• tricalcium phosphate
• xanthan gum
• xylitol
• zinc oxide

As a rule of thumb, if you could not find an ingredient in nature or make it at home, it is a food additive.

🚫 Avoid Protein Concentrates and Isolates

You should also consider avoiding protein concentrates and isolates.

Most meal replacements are made from one or both of these protein sources, which have been mechanically and/or chemically stripped of everything but the protein.

This includes the enzymes, fiber, and other natural digestive aids that help you break them down.

You therefore do not digest them in the same way that you do whole foods, which can affect your gut health.

In fact, studies show that regularly eating protein concentrates and isolates can disrupt your gut microbiome and cause the formation of toxic byproducts in your gut (Nutrients, 2018; Mol Nutr Food Res, 2024).

So instead of ultra-processed protein concentrates or isolates, look for whole food protein sources like egg whites and almonds.

They are easier to digest and absorb.
